CLC Letter in Support of Illinois H.B. 5154

On April 20, 2026, Campaign Legal Center sent a letter to the sponsor of Illinois House Bill 5154, which would require the disclosure of the original sources of big spending in Illinois elections and strengthen Illinois' coordination laws. Our letter details our support for the transparency and coordination policies included in HB 5154 and how the provisions of the bill are consistent with well-established U.S. Supreme Court precedent.
